How to File a Criminal Complaint in Kolkata – Step-by-Step Guide 2026
Complete guide on filing a criminal complaint in Kolkata. Learn procedure at police stations, before magistrates, online options, and your legal rights under BNSS.
Filing a criminal complaint is your first step towards justice when you have been a victim of crime. In Kolkata, you can file at the local police station, before a Judicial Magistrate, or through online portals depending on the nature of the offence.
Criminal complaints in Kolkata fall into three categories: FIRs at police stations for cognizable offences where police can arrest without warrant, complaint cases before a Magistrate for non-cognizable offences, and Zero FIRs at any police station regardless of jurisdiction for serious offences.
Understanding which type to file is crucial as the procedure and legal consequences differ significantly. The choice determines which court or authority handles your case.
Where to File in Kolkata

For cognizable offences, visit the police station with jurisdiction over the area where the offence occurred. Kolkata has 70+ police stations under Kolkata Police Commissionerate, including Lalbazar, Shakespeare Sarani, New Market, Park Street, and local area stations.
Before a Judicial Magistrate
If the police refuse to register FIR, file a complaint directly before a Judicial Magistrate at Bankshall Court or the Chief Judicial Magistrate's court. The Magistrate can order police investigation under Section 156(3) BNSS.

Kolkata's criminal justice system operates through a well-defined hierarchy of courts, each with specific jurisdiction. The Calcutta High Court stands at the apex, followed by the Sessions Courts at Alipore, Bankshall, Sealdah, and various district courts in the suburbs. Magistrate Courts handle less serious offences, while Sessions Courts deal with grave crimes like murder, rape, and dacoity.
The process begins with the filing of an FIR at the local police station, followed by investigation and submission of a chargesheet. The Magistrate then takes cognizance and either commits the case to Sessions Court or tries it summarily depending on the offence's gravity. Throughout this process, the accused has the right to legal representation, bail, and a fair trial under Article 21 of the Constitution.
Kolkata's courts have developed specialized procedures over decades of legal practice. For instance, the Bankshall Court complex houses the City Sessions Court, which handles the majority of criminal cases arising within the Kolkata Police jurisdiction. The Chief Judicial Magistrate Courts in Alipore and other districts manage the preliminary stages of criminal proceedings.
◆ Non-bailable warrants are typically issued for serious offences under the Bharatiya Nyaya Sanhita (BNS)
◆ The accused must be produced before a Magistrate within 24 hours of arrest as per BNSS provisions
◆ Kolkata courts maintain separate calendars for Sessions, Magistrate, and Executive cases
◆ Legal aid is available through the West Bengal State Legal Services Authority headquartered in Kolkata
◆ Victim compensation schemes are actively implemented through the District Legal Services Authority
Evidence and Witness Examination in Criminal Trials
The Bharatiya Sakshya Adhiniyam (BSA), 2023 governs the rules of evidence in criminal trials across Kolkata courts. Evidence is broadly classified as documentary, oral, and electronic. The prosecution bears the burden of proving the accused's guilt beyond reasonable doubt, a cornerstone of criminal jurisprudence that protects innocent individuals from wrongful conviction.
Witness examination follows a structured procedure: examination-in-chief by the party calling the witness, cross-examination by the opposing party, and re-examination to clarify matters arising from cross-examination. Kolkata's trial courts are known for their meticulous approach to witness testimony, often recording evidence in detail to ensure nothing is lost in appeal.
Electronic evidence, including emails, WhatsApp messages, CCTV footage, and call data records, has become increasingly significant in Kolkata's criminal trials. The courts apply the principles of admissibility under Section 65B of the BSA to such evidence. Our legal team at Advocate in Kolkata has extensive experience in presenting and challenging electronic evidence in criminal proceedings.
◆ Documentary evidence must be certified and properly marked before it can be tendered
◆ Hostile witnesses can be cross-examined by the party that called them with court permission
◆ The right against self-incrimination under Article 20(3) protects the accused from being compelled to testify
◆ Medical evidence, including injury reports and autopsy findings, is crucial in cases involving physical harm
◆ Forensic evidence, including DNA analysis and fingerprint matching, carries significant evidentiary weight
Sentencing and Appeals in Criminal Matters
After conviction, the sentencing phase begins. The court considers factors such as the nature and gravity of the offence, the criminal history of the accused, the impact on the victim, and any mitigating circumstances. Kolkata's Sessions Courts have wide discretion in sentencing, ranging from fines and probation to life imprisonment and, in rare cases, the death penalty.
The Bharatiya Nyaya Sanhita prescribes graded punishments for different offences. For example, murder under Section 103 BNS carries life imprisonment or death, while theft under Section 303 BNS is punishable with up to three years of imprisonment. The courts also have the power to order compensation to victims under the BNSS provisions.
Appeals from Magistrate Courts lie to the Sessions Court, while appeals from Sessions Courts go to the Calcutta High Court. The High Court's criminal appellate jurisdiction is vast, allowing it to review both factual and legal findings. A further appeal to the Supreme Court lies on substantial questions of law. The revision jurisdiction allows the High Court to examine the legality and propriety of any proceedings before subordinate courts.
◆ The Calcutta High Court has a dedicated Criminal Appellate Bench that hears appeals in rotation
◆ Mercy petitions can be filed to the Governor of West Bengal and the President of India in death penalty cases
◆ The limitation period for criminal appeals varies depending on the court and type of order
◆ Probation of Offenders Act applies to first-time offenders for certain categories of offences
◆ Kolkata's courts actively use plea bargaining provisions to reduce the burden on the criminal justice system
